wifi: Correct typos and improve doxy (part 1)

Logging system outputs have not been modified (to avoid breaking any parsing scripts), except for a typo in InterferenceHelper.

Here are the list of modifications:

• Finish completing doxy
  • Add description of parameters
  • Add units (also in attribute description)
• Capitalize or camel case when necessary
• Correct indentation
• Remove redundant doxy descriptions for overloaded/implemented methods (already in base class)
• Move doxy to .h for operator overloads
• Use full word instead of abbreviation (e.g. pkt -> packet)
• Fix a couple of typos

As per Stefano's comment, the standard uses different naming conventions for acknowledgment. Here are a few:

• Ack/BlockAck/BlockAckRequest, when it comes to the actual frames and frame variants
• Ack Policy/Normal Ack/Block Ack/Block Ack Request/No Ack, when it comes to fields and subfields
• ack/block ack/block ack request, when it comes to agreements, mechanisms, procedures, policies, transfers, records, ...

In this MR, ht-configuration to yans-wifi-phy are covered, i.e. 90 files.
